Common Prettymouth Puffball

Calostoma fuscum


These fruiting bodies were slightly firm supported by hairy stalks about 50mm tall. The smooth ball caps were about 20 mm wide with a central opening which had a raised star-shaped orange lip.


Spotted in sodden soil on the sloping side of a track.
Occurrence record:


This stalked puffball is called Calostoma or pretty mouth because of the raised orange stoma, which is quite attractive.
The spore-containing peridium is three-layered and protected by a harder cap which falls off at maturity.The inner sac is then exposed and when under pressure, releases its spores through its opening.
Order : Boletales
Family: Calostomataceae
